Description

  

  Verfahren zur Herstellung eines neuen     Monoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines neuen Mono  azofarbstoffes, dadurch gekennzeichnet, dass  man die     Diazoverbindung    von     Anthranilsäure     mit der     2-Methogyacetylamino-5-naphthol-7-          sulfosäure    kuppelt.  



  Der erhaltene Farbstoff stellt ein rot  braunes wasserlösliches Pulver dar und färbt  die animalische Faser in sehr egalen, leb  haften     Orangetönen    von sehr guter Licht  echtheit.  



       Beispiel:     13,7 kg     Anthranilsäure    werden in der  üblichen Weise     diazotiert    und die erhaltene       Diazolösungwird    mit einer mit überschüssigem       Natriumbicarbonat    versetzten Lösung von  32 kg der 2-Methogyacetylamino-5-naphthol-         7-sulfosäure    gekuppelt. Der gebildete Farb  stoff wird in üblicher Weise isoliert und ge  trocknet.



  Process for the preparation of a new monoazo dye. The present patent relates to a process for the preparation of a new mono azo dye, characterized in that the diazo compound of anthranilic acid is coupled with 2-methogyacetylamino-5-naphthol-7-sulfonic acid.



  The dye obtained is a red-brown water-soluble powder and dyes the animal fiber in very level, vivid orange tones of very good light fastness.



       Example: 13.7 kg of anthranilic acid are diazotized in the usual way and the diazo solution obtained is coupled with a solution of 32 kg of 2-methogyacetylamino-5-naphthol-7-sulfonic acid to which excess sodium bicarbonate has been added. The color formed is isolated in the usual way and dried ge.
